User Request for Applications / Bluetooth Obex Push Manager

« on: March 17, 2005, 05:52:17 pm »

Related to this stuff...

It seems that the latest Cacko includes opd (running by default) as well as obextool.  So pushes can now be done from the command-line without adding any extra software, and it seems like this should also make a push GUI a little easier to bang together.

If I could build up enough motivation to learn Qt I could probably bang something simple together... or maybe PyQt is the way to go.

Personal Java/Jeode/J2ME Personal Profile / What's The Lowest Common Denomiator For Java?

« on: February 14, 2005, 10:05:04 pm »

Try me2se for MDIP support. Works for some programs.

Yeah, it doesn't seem bad.  Ran across that in my latest search.

Supports MIDP 1.0, but not MIDP 2.0.  Currently evaluating the cost of wasting my time making it support some of MIDP 2.0.  In particular, the ability to enter decimal numbers is extremely invaluable.  The gaming API is lower on my wishlist.

Personal Java/Jeode/J2ME Personal Profile / What's The Lowest Common Denomiator For Java?

« on: February 10, 2005, 08:28:49 pm »

I should add here since nobody seems to have mentioned it, that there really is no lowest common denominator here.

There are two strains of J2ME:

• CLDC and MIDP are on one side, which is what pretty much all phones support.
• CDC and PP are on the other side, which is what pretty much all PDAs (except for Palm) support.  As has been mentioned, CDC and PP is basically a subset of J2SE.

The lowest common denominator, if you had to give one, would be CLDC.  But CLDC has no GUI functionality at all, so isn't really suitable for anything except libraries and such.  

On the GUI side, you're pretty much screwed.  Any GUI classes you can use to make MIDP apps are not available in PP, and any GUI classes you can use to make PP apps are not available in MIDP.  No lowest common denominator whatsoever.

It was actually for this reason that last year, I asked whether anyone knew of ways to run MIDP stuff inside PP (supposing that someone wrote a compatibility layer, it would be quite possible to do.)  But since nobody answered and Google couldn't find it, I assume that such a thing doesn't exist.

If you want to support both sides then, you should design your application using an MVC paradigm to save work.  Write an MIDP view, a PP view, and a single model which both views can use.

Angstrom & OpenZaurus / Suspend Button Issues In Oz 3.5.2

« on: February 07, 2005, 09:02:36 pm »

I added a line to the apmd_proxy to dump its command-line arguments to a log file, and what I'm finding is this:

• Hitting the suspend button twice within about a minute or so (i.e., normal PDA usage) does not result in apmd_proxy being called at all.
• Choosing Suspend from the menu does.
• Waiting about five minutes after hitting the suspend button does.

It's a bit annoying, as the system turns off my Bluetooth card in all cases, but since I'm not actually getting any APM events, I can't make the card eject/reinsert on resume in all cases, so I often end up having to remove the card manually.  Yuck.

So is this a known issue?

Angstrom & OpenZaurus / 3.5.2 Upgrades

« on: February 07, 2005, 06:05:44 pm »

Newer versions of anything with the word 'bluetooth' in them would be good.  I reckon I must have spotted about half a dozen bugs in various apps, particularly the bluetooth manager...

Angstrom & OpenZaurus / Bluetooth With Oz3.5.2

« on: January 29, 2005, 12:02:39 am »

I just noticed a similar problem and it doesn't seem to matter if you use something like OPIE's bluepin, or a simpler givepin script.

Note that OPIE's bluepin script seems to return ERR on the first line of text, which may be an issue as well.  But even a well-formed givepin script which does nothing but print out the value doesn't seem to work. :-/

Stab in the dark: try changing "security auto" to "security user" in hcid.conf. :-)

Angstrom & OpenZaurus / Oz 3.5.2 Bluetooth Bugs

« on: January 27, 2005, 04:53:16 pm »

Two quick ones in case others encounter the same issues:

1. The OPIE Bluetooth manager in this version doesn't fill the full screen (you get a 200x200 window on a massive blank background)
2. /etc/pcmcia/bluetooth should say /sbin/hciattach, not /usr/sbin/hciattach.

General Discussion / Who's Got To Go? Qtopia, Opie?

« on: January 20, 2005, 09:08:57 pm »

I hate to make a choice between forks as in most cases, there is something each side brings that the other doesn't.

But at the moment, I think I'd want to keep OPIE, even if I don't use it myself yet.  Generally it's not such a good idea to stifle development on any platform, least of all anything related to PDAs, where innovation is a good thing, and something which is far too uncommon.  Qtopia might be source-available, but unless they actually accept the patches people make, is it really "open"? :-/

Linux Issues / Syncing With Kitchensync On Kde 3.3.1

« on: January 20, 2005, 07:04:07 am »

Hmm.  You're lucky.  I can't even get KitchenSync to do anything when I press the sync button.  No errors, no messages, nothing but a "Ready" screen.  I can ping the Zaurus on the same IP address as I've entered in KitchenSync, but something must really be amiss.

Or perhaps the KitchenSync in the KDE 3.4 beta is simply broken.

Personal Java/Jeode/J2ME Personal Profile / Midp

« on: January 15, 2005, 10:57:02 am »

For various reasons, it would be good to have the ability to run MIDP apps on the Zaurus.  Unfortunately for us, PP is not a superset of MIDP, and lacks much of the UI stuff.

I figure, though, that it must be possible to implement a large amount of MIDP using PP.  I've seen some stuff for running MIDP on J2SE, but never on PP...

Does anyone know if something is available for bridging this gap?

Sharp ROMs / Cacko: Network Icon Vanishes On Resume

« on: January 11, 2005, 11:44:23 pm »

On Cacko 1.22, I've noticed that quite often, in fact almost 100% of the time, when I suspend and resume the Zaurus, the icon I should be clicking on to get the connection dialog to appear, vanishes from site while the device is in the process of resuming.

Removing the Bluetooth card and plugging it in again doesn't seem to make it come back, but if I go to the network settings, the icon reappears while the settings app starts up, and then works fine.

My assumption is that the icon is set up to disappear when networking devices are ejected, and reappear when they are inserted.  Is there any way to fix it so that it works like this?

Sharp ROMs / Cacko: Default Route For Usb Network

« on: January 11, 2005, 11:41:24 pm »

Every time I suspend/restart, I need to reactivate the default route...

Code: [Select]

# route add default gw 192.168.129.1
If I don't do this, I get no networking beyond the box it's connected to.  It's come to the point where I always leave a console open so that it saves time each resume. :-)

What's the best way to set this up as the default route at all times?  I thought about putting it in the APM scripts, but I'm not entirely sure how that will interact when a "real" network is connected to.

Also, is there any way to avoid both NetFront and Opera saying "no network connection found", when there is clearly a working network connection?

Sharp ROMs / Konqueror/embedded On Cacko

« on: January 11, 2005, 09:04:53 pm »

The version of Konqueror/Embedded available from this feed seems to be built for the default Sharp ROM, and causes some sort of kernel panic when running on Cacko.

I figure the fix would just be to rebuild the module it's loading against Cacko's kernel headers, but before I figure out how hard this is to do, has anyone else already done it? :-)

EDIT: Actually, the module in question was /usr/local/sbin/kbdsim.o, which wasn't removed when I uninstalled Konq/E.  It looks like it comes on the ROM... if that's the case, there could be a more serious problem going on.

Cxx0 General discussions / Imageon 100 Acceleration

« on: January 09, 2005, 08:36:35 pm »

Does anyone know exactly how much acceleration we get out of the Imageon 100?

For instance, the Imageon 100 is supposed to support hardware MPEG-4 decoding, but do any of the video players actually take advantage of it?  Actually... is the support in the kernel in the first place?

I'm just curious whether transcoding all videos to MPEG-4 format might give bigger performance improvements that I might expect. :-)

Angstrom & OpenZaurus / Install Problem

« on: January 02, 2005, 09:41:44 pm »

Interesting, I have another problem in the same way.  Moved from Cacko to OpenZaurus, everything installs fine, until it gets to "starting opie" or similar, and then I get an empty black screen.

My theory was the same, that it might be related to flash size.  Maybe 27 just won't work.
